Simulation methodology for occupant injury of armoured vehicles subjected to a mine blast

Simulating the dynamic response of an armoured vehicle and occupants subjected to a mine blast

To simulate the dynamic response of occupants in a military vehicle subjected to a mine blast several systems are involved, such as the loading of the mine blast, the structural response of the vehicle and the motion response of the occupants. Furthermore special techniques are required for the coupling between the different systems, for example...

Testing of full scale composite journal bearings for offshore underwater applications

In the offshore industry, fibre reinforced sliding journal bearings are increasingly used due to their low-maintenance and self-lubricating characteristics. To be able to use the bearings in the rough offshore environment, under heavy loading, full scale tests are essential to assess the friction and wear rate development during use. For this...

Effect of gage length on failure strain

Failure prediction in crash analyses of ships has traditionally made use of an equation that relates the failure strain to the gage length and material thickness. The equation is derived based on the idea that a neck ( a localization of strain) is a fixed size relative to the thickness and that it can be homogenized over a larger gage section....

Maritime improvised explosive devices, modelling and large scale trials

Maritime Improvised Explosive Devices (MIEDs) such as small boats filled with explosives are likely to be a threat in future combat scenarios. For example the suicide attack against the USS Cole in Yemen (October 2000) has shown how disastrous MIEDs can be. With relatively simple means a complete compartment of a ship can be flooded, with...
